Treatment could save the NHS £3.1 billion every year More than 200,000 patients in the UK suffer with chronic wounds Healing time can be reduced by a third Healing times for skin ulcers and bedsores can be reduced by a third with the use of low-intensity ultrasound, scientists from the University of Sheffield and University of Bristol have found. Researchers from the University of Sheffield's Department of Biomedical Science discovered the ultrasound transmits a vibration through the skin and wakes up cells in wounds helping to stimulate and accelerate the healing ...

When two different sized galaxies smash together, the larger galaxy stops the smaller one making new stars, according to a study of more than 20,000 merging galaxies. The research, published today, also found that when two galaxies of the same size collide, both galaxies produce stars at a much faster rate. Astrophysicist Luke Davies, from The University of Western Australia node of the International Centre for Radio Astronomy Research (ICRAR), says our nearest major galactic neighbour, Andromeda, is hurtling on a collision course with the Milky Way at about 400,000 ...

As the world's leaders gather in Addis Ababa, Ethiopia, for the Financing for Development Conference [1], a study published in The Lancet demonstrates that a new approach is needed for classifying funding that reflects the function the funding serves, rather than the specific disease or country. The study is the first in-depth assessment of how donor funding is spent on global versus country-specific functions of health [2]. The paper also presents an expanded definition of official development assistance (ODA) for health, which is used to identify important underfunded ...

As experts debate the slow response to the Ebola outbreak in West Africa and call for better international coordination, a new analysis estimates that $22 billion was spent on global health aid in 2013, yet only a fifth of this went toward such global imperatives as research on diseases that disproportionally affect the poor, outbreak preparedness and global health leadership. The analysis, by Dean Jamison, PhD, a global health economist at UC San Francisco (UCSF); Lawrence Summers, PhD, a former US Treasury Secretary now at Harvard University; and researchers at SEEK ...

ORLANDO, FL - Surgeries related to overuse elbow injuries, i.e. Tommy John Surgery, are more common among youth athletes than previously believed, according to research presented today at the American Orthopaedic Society for Sports Medicine's (AOSSM) Annual Meeting in Orlando, Florida. "Our results showed that 15-19 year-olds accounted for 56.7 percent of the Ulnar Collateral Ligament Reconstruction (UCLR) or Tommy John surgeries performed in the U.S. between 2007-2011. This is a significant increase over time with an average increase of 9.12 percent per year," said lead ...

ORLANDO, FL - Athletes who've had lower extremity surgeries before going on to play in college, might be at a higher risk for another surgery independent of gender and sport, say researchers presenting their work today at the American Orthopaedic Society for Sports Medicine's (AOSSM) Annual Meeting in Orlando, FL. "This is the first study to look at the relationship between precollegiate surgery and future injury requiring surgery in collegiate athletes. Our results suggest that athletes injured before college might be left with a functional deficit that puts them at ...

Nutrition support professionals who are well-versed in proper documentation of malnutrition diagnoses in hospital patients can help ensure that hospitals receive maximum funding for patient care according to a new review. The review, recently published in Nutrition in Clinical Practice (NCP), a peer-reviewed, interdisciplinary journal of the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) that publishes articles about the scientific basis and clinical application of nutrition and nutrition support, found that proper documentation and coding of malnutrition ...

ORLANDO, FL - Patients treated surgically for a hamstring rupture demonstrated better results than those treated only with therapy, according to a study presented today at the American Orthopaedic Society for Sports Medicine's (AOSSM) Annual Meeting in Orlando, FL. "Overall, patients in this study treated with surgery had a trend towards better lower extremity function as well as a higher likelihood of returning to re-injury activities than those treated non-surgically," commented corresponding author Joshua Olsen, MD, from the New England Baptist Hospital. "Most notably, ...

ORLANDO, FL - Outcomes following the arthroscopic repair of rotator cuff tears in older athletes appears to be successful a majority of the time, according to research presented today at the American Orthopaedic Society for Sports Medicine's (AOSSM) Annual Meeting in Orlando, Florida. "Seventy-seven percent of our patients who had an arthroscopic repair of a full thickness rotator cuff tear, were able to return to their sport at a similar level of intensity," said lead author, Peter Millett, MD, MSc, from the Steadman Philippon Research Institute in Vail, Colorado. Forty-nine ...

OAK RIDGE, Tenn., July 10, 2015 -- Groundbreaking work at two Department of Energy national laboratories has confirmed plutonium's magnetism, which scientists have long theorized but have never been able to experimentally observe. The advances that enabled the discovery hold great promise for materials, energy and computing applications. Plutonium was first produced in 1940 and its unstable nucleus allows it to undergo fission, making it useful for nuclear fuels as well as for nuclear weapons. Much less known, however, is that the electronic cloud surrounding the plutonium ...

Five billion years ago, a great disturbance rocked a region near the monster black hole at the center of galaxy 3C 279. On June 14, the pulse of high-energy light produced by this event finally arrived at Earth, setting off detectors aboard NASA's Fermi Gamma-ray Space Telescope and other satellites. Astronomers around the world turned instruments toward the galaxy to observe this brief but record-setting flare in greater detail. "One day 3C 279 was just one of many active galaxies we see, and the next day it was the brightest thing in the gamma-ray sky," said Sara ...

This news release is available in German. Are wind farms harmful to humans? Some believe so, others refute this; this controversial topic makes emotions run high. To give the debate more objectivity, an international team of experts dealt with the fundamentals of hearing in the lower limit range of the audible frequency range (i.e. infrasound), but also in the upper limit range (i.e. ultrasound). The project, which is part of the European Metrology Research Programme (EMRP), was coordinated by the Physikalisch-Technische Bundesanstalt (PTB). At PTB, not only acoustics ...

July 10, 2015 - For children with cleft lip and palate, the chances of undergoing secondary surgery vary depending on the center where they're treated, reports a study in Plastic and Reconstructive Surgery--Global Open®, the official open-access medical journal of the American Society of Plastic Surgeons (ASPS). When secondary surgeries are performed, they don't necessarily improve the child's final facial appearance, according to the new research by ASPS Member Surgeon Dr. Thomas J. Sitzman of Cincinnati Children's Hospital Medical Center and colleagues. Secondary ...

Random-access memory, or RAM, is where computers like to store the data they're working on. A processor can retrieve data from RAM tens of thousands of times more rapidly than it can from the computer's disk drive. But in the age of big data, data sets are often much too large to fit in a single computer's RAM. The data describing a single human genome would take up the RAM of somewhere between 40 and 100 typical computers. Flash memory -- the type of memory used by most portable devices -- could provide an alternative to conventional RAM for big-data applications. It's ...

LEXINGTON, Ky. (Jul. 10, 2015) -- Macrophages are cellular sentinels in the body, assigned to identify "attacks" from viruses, bacteria, or fungi and sound the alarm when they are present. However, these cells are a "double edged sword" in spinal cord injury, providing both neural repair-promoting properties and pathological functions that destroy neuronal tissue "We know from previous research that macrophages are versatile, and signals at the injury site can stimulate repair or destruction--or confusingly, both," said John Gensel Ph.D., Assistant Professor of Physiology ...

This news release is available in Spanish. Scientists at the Centre for Genomic Regulation (CRG), the research company Starlab and the group BR::AC (Barcelona Research Art & Creation) of the University of Barcelona developed a device that produces sounds from brain signals. This highly interdisciplinary team is led by Mara Dierssen, head of the Cellular & Systems Neurobiology group at CRG.

The great white shark (Carcharodon carcharias) has a terrifying reputation. Shark attacks, though very rare, loom large in our imaginations, drawing intense media attention when they occur. Recent injuries in North Carolina are putting sharks in the limelight again. But going after sharks à la Jaws is not the best way to protect people in the water, said shark researchers. California scientists found that the risk of white shark attack for individual ocean users in California has fallen strikingly, by over 91 percent, since 1950, in a study to be published online ...
